Modern engines introduce more contaminants into oil than their predecessors. To compound the issue, oil sumps are shrinking, leaving fewer detergents and dispersants to help fight the by-products of the internal combustion process. An oil filter’s capacity must improve to contend with the additional contaminants. Capacity refers to the amount of contaminants a filter can hold while still remaining effective.
To understand the significance of capacity, it’s helpful to know the basics of oil filtration. Clean oil is vital to keeping engines running properly. The oil filter must remove contaminants introduced into the oil and prevent them from reaching sensitive engine parts without restricting normal oil flow. Internal sources of contamination include wear products from the rubbing surfaces of the engine, and degradation of the oil itself. To provide top-notch performance, a filter must be constructed with the optimum balance of capacity, efficiency, flow and durability.
Advanced Media Technology
AMSOIL Ea Oil Filters are engineered using full-synthetic media that features smaller fibers compared to the cellulose and blended media found in other filters. The smaller fibers have a controlled size and shape, providing greater efficiency, capacity and durability. The media in Ea Oil Filters provides up to two times greater capacity than competing filter brands.Absolute Efficiency
Efficiency describes the filter’s ability to capture contaminants. The more efficient a filter, the more contaminants it re-moves from the oil. Manufacturers typically report their filters’ efficiencies as the percentage of contaminants 20 microns and larger removed from oil. Filters using traditional media are often only 40 to 80 percent efficient at 20 microns.In extensive testing, the full line of AMSOIL Ea Oil Filters achieves a near- perfect absolute efficiency rating of 98.7 per-cent at 20 microns, making each filter among the most efficient available for autos/light trucks.
Improved Flow
Flow is restricted as the spacing in the filter media is made smaller to provide greater efficiency. The unique design and full-synthetic media in AMSOIL Ea Oil Filters allow decreased space between fibers without restricting flow. This provides exceptional cold-start performance and ensures proper levels of lubrication throughout the engine.Durable Construction
Over the service life of a cellulose filter, hot oil degrades the resins that bind the media. Ea Oil Filters’ full-synthetic media is backed with a wire screen that is pleated with the media for superior strength. Ea Oil Filters are constructed with HNBR nitrite gaskets that are fully tested to extreme distances in numerous severe environments. The filters also feature fully tucked seams, a molded element seal, roll-formed threads and a long-lasting premium-grade silicone anti- drain valve.AMSOIL Ea Oil Filters
